The project: IMEG provided structural engineering design for this multi-phase, multi-construction contract expansion of a conventional water treatment plant to 540 million gallons per day (MGD).

The goal: The objective was to significantly expand treatment capacity and modernize core process infrastructure while minimizing disruptions to ongoing plant operations.

Scope of work: The project consisted of expansion and improvements for core process facilities including the Stage IV Filters Complex, 350 MGD high service pumping and 64 MG clearwell storage improvements, flocculation/sedimentation expansion, conversion to plate settlers and new chemical headworks facilities. Filter improvements included a new 16-cell filter complex and galleries to accommodate planned BAF process conversion. Design also included four new ground storage tanks providing a total 62.5 MG of storage. Detailed demolition and construction sequencing were required to facilitate plant tie ins at key conveyance structures to minimize impact on operations.

The outcome: The plant expansion supports long-term water treatment needs by increasing capacity and improving operational flexibility. Careful phasing and tie-in planning ensured that critical facilities remained online throughout construction.
